Do the same for the file or folder you want to compare in the 2 nd File or Folder space. System.IO.DirectoryInfo dir2 = new System.IO.DirectoryInfo(pathB) in 1 st File or Folder, select Browse and choose the file or folder that you want to compare. String pathA = pathB = dir1 = new System.IO.DirectoryInfo(pathA) on a local drive and change these file paths. Create two identical or different temporary folders In a real-world scenario, you should modify this comparer to perform a more rigorous equality check.

It just uses the name and length in bytes of each file to determine whether the contents of each folder are identical or not. Windows : Windows script to compare folders recursivelyTo Access My Live Chat Page, On Google, Search for 'hows tech developer connect'I have a hidden featur.

The FileComparer class shown here demonstrates how to use a custom comparer class together with the Standard Query Operators. The techniques shown here can be adapted to compare sequences of objects of any type.
